Comparing two double numbers

The following code executes the

else

statement because the

float

numbers are different

if (strval(0.000000000035436064) == strval(0.000000000035436064000001)) {
    echo 'if';
} else {
    echo 'else';
}

But if we add one

in front of the last digit of the second number, then

if

statement will be executed

if (strval(0.000000000035436064) == strval(0.0000000000354360640000001)) {
    echo 'if';
} else {
    echo 'else';
}

Note:

The above code is one of the best solutions to compare float numbers
